XUnmapWindow(3)			XLIB FUNCTIONS		       XUnmapWindow(3)

       XUnmapWindow, XUnmapSubwindows - unmap windows

       int XUnmapWindow(Display *display, Window w);

       int XUnmapSubwindows(Display *display, Window w);

       display	 Specifies the connection to the X server.

       w	 Specifies the window.

       The XUnmapWindow function unmaps the specified window and causes the X
       server to generate an UnmapNotify event.	 If the specified window is
       already unmapped, XUnmapWindow has no effect.  Normal exposure process‐
       ing on formerly obscured windows is performed.  Any child window will
       no longer be visible until another map call is made on the parent.  In
       other words, the subwindows are still mapped but are not visible until
       the parent is mapped.  Unmapping a window will generate Expose events
       on windows that were formerly obscured by it.

       XUnmapWindow can generate a BadWindow error.

       The XUnmapSubwindows function unmaps all subwindows for the specified
       window in bottom-to-top stacking order.	It causes the X server to gen‐
       erate an UnmapNotify event on each subwindow and Expose events on for‐
       merly obscured windows.	Using this function is much more efficient
       than unmapping multiple windows one at a time because the server needs
       to perform much of the work only once, for all of the windows, rather
       than for each window.

       XUnmapSubwindows can generate a BadWindow error.

       BadWindow A value for a Window argument does not name a defined Window.
